| Abstract: | This paper describes components of communication system of rail transportation and basic concept of Fault Tree Analysis(FTA) method.After analyzing the functional framework,research on communication system is implemented and Fault Tree of communication system is established.The main factors affecting the failure of communication system can be determined by qualitative analysis in which the minimum cut set analysis(MCSA) is employed,meanwhile,quantitative way is also presented.According the outcome of reliability research,Fault Tree Analysis(FTA) method is very efficient for improving reliability of communication system. |
